Years ago, I lived in a building in a large city. There was another building not far from mine. A woman lived there. I had never met her, but I could see her sit by the window each afternoon, drinking or reading.
After several months, I began to find that her window was dirty. Everything was unclear through the dirty window. I would say to myself, “What a lazy woman! I want to know why she doesn’t wash her window. It really looks terrible.”
One bright morning, I decided to clean my flat, including the window. I worked the whole morning. When I finished the cleaning, I sat down by the window with a cup of coffee for a rest. What a surprise! Everything in the woman’s flat could be seen clearly. Her window was clean!
I began to understand. I watched the woman’s window from my own dirty window. That’s the problem!
This is quite an important lesson for me. How often do I look at and criticize(批评) others through the dirty window of my heart?
From then on, whenever I want to judge someone, I ask myself first, “Am I looking at him through my dirty window?” Then I try to clean the window of my own world so that I may see others’ world more clearly.
